Active torsional dampter for rotating shafts

A method of reducing vibration in a rotatable component, comprising:

• providing a rotatable shaft;
• disposing a rotatable measurement interface on the rotatable shaft;
• rotating the rotatable shaft;
• operating the rotatable measurement interface to measure a strain on the rotatable shaft;
• transmitting the measured strain to a control system component;
• determining a corrective torque as a function of the measured strain;
• and
• imparting the corrective torque to the rotatable shaft.

An active torsion damper control system, comprising:

• a rotatable component;
• a rotatable measurement interface disposed on the rotatable component, the rotatable measurement interface having a measuring component configured to measure a strain of the rotatable component;
• a torque management computer configured to determine a corrective torque as a function of the measured strain;
• and
• a correction motor configured to impart the corrective torque on the rotatable component.
